sf6 insulated switchgear check for leaks for 110kv

Each gas compartment is fitted with an independent self-sealing valve, which ensures SF6 gas of GIS won't leak while connecting or disconnecting with the gas-charging device. Since GIS won't be affected by external environment, such as dust, humidity, etc., the maintenance is pretty low, to some extent, maintenance-free.
